+ * @Test_Aim@ Test that non-secure interrupts do not interrupt secure service
+ * requests.
+ *
+ * 1. Register a handler for the non-secure timer interrupt.
+ *
+ * 2. Program the non-secure timer to fire in 500 ms.
+ *
+ * 3. Make a long-running (> 500 ms) fast secure service request.
+ * This is achieved by requesting the timer sleep service in Cactus
+ * with a 1 second sleep delay.
+ *
+ * 4. While servicing the timer sleep request, the non-secure timer should
+ * fire but not interrupt Cactus.
+ *
+ * 5. Once back in TFTF, check the response from Cactus, which shows whether the
+ * secure service indeed ran to completion.
+ *
+ * 6. Also check whether the pending non-secure timer interrupt successfully got
+ * handled in TFTF.
